I have a Tiberius red dot sight on my AUG. It kinda looks like a scope but it isnt. I believe it's 1X30mm. There made for the old version of the TAC 9 paintball gun. You can get them cheap too. For the open or close type, you should be keeping both eyes open as you look through it. The dot should almost appear as if it was a laser pointing at your target, just only uoi can see it. For durablility, I would go with the close style. More rugged.
